The show was a month before the song was released as the fourth single from the band’s album, Never Mind The Bollocks.

Due to their secrecy, the band were billed on a poster as ‘A Mystery Band of International Repute’.

The footage has been released by Julien Temple, director of the Pistols film The Great Rock’n’Roll Swindle.

It is featured on a new deluxe box set of Never Mind The Bollocks, which is being released to celebrate the album’s 35th anniversary.

Temple said: “The performance was shot using one camera and shows the extraordinary captivating quality of the band at the time.

“There was shock in the room, it was hypnotising, contagious, and unfolded right in front of you.

“The Pistols arrived in Penzance unannounced and the audience couldn’t believe what they were getting.”

Locals were told to pay their money and take a chance as rumours quickly spread that the Rolling Stones were in town.
